LhArc compression tool for the Commodore Amiga, this is only a pre-release so there's no real documentation yet. It is 100% compatible with LhArc version 1.13c (MSDOS) and Amiga LhArc (The Italian CLI version), only it is more than twice as fast !!! I hope you will understand how to use it anyway, but here's some tips to get you going: EXTRACTING If you want to extract files from an existing archive, first select 'Open Archive' from the Project menu or press Right-Amiga+O or just press 'O'. Then select the file from the file requester by entering the source directory in the Dir gadget and then click twice on the file you want to extract from, or enter the file's name in the File gadget and press RETURN. Then click on the files you want to extract (clicking once selects, clicking a second time deselects again), or use the 'Mark all', 'UnMark all' and 'Mark...' gadgets. The 'Mark...' gadgets allow you to enter an ARP-pattern mask to select certain files. (For example. '*.c' will select all files ending in '.c' and 'a*z' will select all files that begin with an 'a' and end with a 'z', detailed explanations of the pattern matching functions will be in the final documentation). When you have marked (highlighted) all files you want to extract, click on the 'Extract' gadget. Now you will be asked where to put the extracted files, select a directory and click on the 'OK' gadget. Now LhArcA will extract your files! If you want LhArcA to consider extended filenames, select 'Extended filenames' in the Settings menu. CREATING AN ARCHIVE When you want to create a new archive, select 'New archive' in the Project menu, then enter the destination directory and archive name. NOTE: In this pre-release you must append '.lzh' after the filename, otherwise LhArcA cannot open it for extraction! This will be fixed in the final release. Then do just like you do when you add files to an existing archive. (Described below). ADDING FILES TO AN EXISTING ARCHIVE This is easy, first open the archive as when extracting (see above), then click on the 'Add files' gadget and then select the files you like to add. You can select as many files as you like and in as many directories you like. If you want pathnames to be stored, select 'Extended filenames' in the Settings menu and then set 'Home directory' to the part of the pathname that should not be stored. (Not enough space to describe this here, wait for the final version) ADDITIONAL NOTES The final version (this is the only pre-release I intend to release), there will be all the features found in other archivers (including PkAZip), and more. LhArcA is FASTER than PkAZip!!! (About 15%), and also more effective. To make it even faster I am working on some new search algorithms which will (hopefully) be finished until the final release!!! Also in the final release there will be the option to issue archiver commands directly from the CLI command line (as Zoo, Arc, LhArc etc.), my intention is to make a program everybody can use, both novices and experts. (Though this version may be a little hard to understand, I will add some online help stuff in the final version). Also it will be possible to create SFX-archives (self-extracting archives), and more.... Anyway, if you have any ideas for improvements, or find any bugs (I have sorted out most of them now, there are (I hope) no serious bugs left, just some things that need to be more polished). Anyway hope you like this, because it took be two months to get this far!! If you like it, PLEASE consider sending me a contribution, look in the About... text for more details. SYSTEM REQUIREMENTS: You'll need: * Arp.library (Version 39.1 is included in this archive). * An Amiga with at least 512K of RAM. * You must have ASSIGNed 't:' somewhere. (Preferably to RAM:, to do this, enter the command 'ASSIGN t: ram:' before running LhArcA. INSTALLING To install LhArcA, extract the files from this archive, then execute the following commands from CLI: copy Arp.library to libs: delete Arp.library This will move the Arp.library to where it should be.
